Abstract (en)

[origin: US2009164614A1] Techniques are described to determine clients residing behind LDNS resolvers. Web beacons instruct clients to retrieve zero-content images at unique hostnames. A request to the hostname is made by a client to an LDNS resolver. The LDNS sends the request to an authoritative server/beacon resolver for the hostname. The beacon resolver records the hostname with the LDNS resolver's IP address and responds with an IP address of a beacon collection server that is forwarded to the client by the LDNS. The client sends a request containing the unique hostname to the beacon collection server. The beacon collection server records the IP address of the client and the hostname. An aggregation server collects data from the beacon resolver and the beacon collection server. Using the hostnames as keys, IP addresses of clients are mapped to IP addresses of LDNS resolvers. Mapped data is exported to load balancing servers to determine routing.
